Abstract (en)
[origin: EP0429974A1] The water-resistant control device for a timepiece is housed in a case (20) and comprises a crown (46) rotating about a tube (21). The crown comprises a head (10), a central part (23) and a lateral skirt (12) which are made in a single piece. The inner wall (11) of the skirt has a cylindrical surface over its entire height. <??>A gasket (13) having the form of an annular band surrounding the tube has, on its inner part, an annular projection (16) interacting with an annular slot (15) made in the tube. The outer part of the said band is shaped so that, regardless of the axial position of the crown (46), the lower edge (24) presented by the inner wall of the skirt is always in contact with the said outer part of the band. <??>The device makes it possible to correct the data displayed by the timepiece, while offering excellent reliability with respect to the water resistance it provides.
